Vacuum freeze-drying technology, also known as freeze-drying or sublimation drying, is a method of pre freezing water containing materials and then sublimating them in a vacuum state. After freeze-drying, the original biological and chemical properties of the item remain basically unchanged, making it easy to store for a long time. After adding water, it can be restored to its original form before freeze-drying and maintain its original biochemical properties. Therefore, freeze-drying technology has been widely applied in fields such as chemical industry, biological products, and food freeze dryers

1. Refrigeration is adopted globallyLinde Hampson technology, equipped with a subcooler (utilizing subcooling for secondary cooling), has high refrigeration efficiency;
2. Use environmentally friendly refrigerants (which definitely do not contain refrigerants prohibited by the country, and some manufacturers still use a mixed refrigerant scheme with a ratio of R12 and R22 prohibited by the country);
3. Refrigeration temperature:
3.1 Standard cold trap temperature (unloaded): ≤ -60 ℃, room temperature ≤28℃；
3.2 Extreme cold trap temperature (unloaded): ≤ -65 ℃, room temperature ≤ 25 ℃;
4. Adopting a 7-inch touch screen, the display is intuitive, the operation is simple, and there is no need to define inexplicable button selections.
5. Support freeze-drying data curve recording function.
6. It is possible to set the temperature requirements for the cold trap when starting the vacuum pump, to avoid starting the vacuum pump when the cold trap temperature has not reached the effective low-temperature water capture performance, which may cause water to enter the vacuum pump;
7. Equipped with an additional set of sensors that can be used to measure sample temperature and record data.
8. Temperature and vacuum degree have correction functions;
9. Equipped with vacuum pressure display unit switching, supporting Mbar, Pa, Torr

10. Free upgrade of electric defrosting function

TF-FD-1 has five basic configurations: regular type, capped type, regular multi manifold, capped multi manifold, and T-shaped multi manifold (24 pieces). Differences in loading material forms:

A: Ordinary type, suitable for loading bulk materials.

B: Cap type, suitable for loading penicillin bottled materials.

C: Ordinary multi manifold, suitable for loading external bottled materials.

D: Sealed multi manifold, suitable for loading bulk materials, bottled materials, and external bottled materials.

E: T-shaped multi manifold, suitable for loading external bottles and safetyBottled materials.

Five types of freeze-drying samples: water-soluble solution, suspension or paste like substance, eutectic point temperature above -20 degrees. If the eutectic point temperature is below -20 degrees, a cold trap temperature of -80 degrees should be selected
